About the project

Seqwater is delivering the approximate 111 kilometre Toowoomba to Warwick Pipeline (the pipeline) on behalf of the Queensland Government.

The Queensland Government has confirmed more than $300 million in funding for the project. The pipeline investment will boost water security in the Toowoomba and Southern Downs regions. Seqwater will construct, own, maintain and operate the pipeline which is expected to be ready in 2027, weather and construction conditions permitting.

Seqwater delivered the detailed design and preparatory works for the pipeline in April 2022, which included survey, ecological and geotechnical investigations, capital cost estimates, a review of environment and heritage approvals.

The pipeline will transfer raw water from just upstream of Mount Kynoch Water Treatment Plant (Toowoomba) to Warwick Reservoir (near Leslie Dam). The water will be sourced from Wivenhoe Dam via the existing Wivenhoe to Cressbrook pipeline and other water infrastructure owned by Toowoomba Regional Council.

The pipeline will run underground along existing road reserves and easements for most of its route. Some strips of property along the route will need to be temporarily or permanently acquired for safety or efficiency reasons. Seqwater will speak to affected property owners as details of the route are finalised.

For more information about why the pipeline is needed and its background, please see the Department of Regional Development, Manufacturing and Water project website.

Design

Detailed design is progressing and reaching the final stages of completion, as the team continue to progress negotiations with impacted landowners, as well as with Toowoomba and Southern Downs Regional councils on easements.

Procurement

We have also been working with our shortlisted tenderers to identify risks and opportunities for delivery, ensuring the pipeline meets the highest standards of quality, safety, efficiency and reliability. Construction contract award is planned for late 2025, and we are continuing to build the list of interested local contractors that will be provided to the Head Contractor once appointed. Thank you to those who have already registered.

Suppliers and contractors can still register interest in the project by signing up here or via the link on the webpage below.

    Toowoomba to Warwick Pipeline Project - procurement update

    Design and planning works are continuing for the Toowoomba to Warwick Pipeline project to boost water security in the Toowoomba and Southern Downs regions.

    Once complete, the underground pipeline will facilitate a water supply to Cambooya, Greenmount, Nobby and Clifton and serve as a drought contingency water supply for residents within the Southern Downs Regional Council areas of Warwick, Allora, Yangan, and by carting south to Stanthorpe and Killarney. Work on the pipeline is due to commence in 2025, and Seqwater will continue to keep the community informed as the project progresses.

    Seqwater is working towards the appointment of a suitably qualified head contractor to deliver the construction phase of the project. A market expression of interest was recently completed, and the Request for Tender has now been released to shortlisted construction firms.

    In selecting a head contractor, Seqwater will give weighted favour to contractors that commit to engaging local subcontractors and suppliers.

    The project will involve trades associated with pipeline installation, civil works, fencing, traffic control, concrete works, reservoir and pump station construction and is estimated to support an average of 400 jobs during the construction phase.

    Local contractors and suppliers are encouraged to register their interest via our website at www.seqwater.com.au/toowoomba-warwick-pipeline-project-registration-form to be added to a register which will be provided to the head contractor, once appointed.

    If you would like more information on the project, contact the project team via 07 3432 7000 (during business hours) or email [email protected].

    What preparation work has already been completed?

    Seqwater completed the preparatory works for the Toowoomba to Warwick Pipeline on behalf of the Queensland Government. The team delivered the preparatory works and detailed design for the pipeline in April 2022 which included survey, ecological and geotechnical investigations, capital cost estimates, a review of environment and heritage approvals, and more.

    What will the pipeline route be? Is it going by my house?

    Seqwater is currently undertaking detailed investigations, including geotechnical, environmental and topographical surveys to finalise the pipeline route and design.

    The pipeline will run underground along existing road reserves and easements for most of its route. There are some locations where that is not possible, and the project will need to temporarily or permanently acquire part of a property for safety or efficiency reasons. Seqwater will speak to affected property owners as details of the route are finalised. Once the design and route are finalised, we will share the details with the community.

    The approximate 111 kilometre pipeline will transfer raw water from just upstream of Mount Kynoch Water Treatment Plant (Toowoomba) to Warwick Reservoir (near Leslie Dam). The water will be sourced from Wivenhoe Dam via the existing Wivenhoe to Cressbrook pipeline and other water infrastructure owned by the Toowoomba Regional Council.

    The major components of the project are:

    • pipeline connection from Toowoomba Regional Council’s Pechey Pipeline (just upstream of Mt Kynoch Water Treatment Plant)
    • approximately 111 kilometre pipeline from the connection point with Pechey Pipeline to the Warwick Reservoir
    • two reservoirs at the northern end of the pipeline, each holding 3 megalitres of water
    • offtakes at the Toowoomba Regional Council towns of Cambooya, Greenmount, Nobby, Clifton, with state funding for water treatment facilities
    • one intermediate pump station and balance tank enroute
    • a pipeline connecting Allora borefield supply to the main pipeline
    • pipeline termination at a new 15 megalitre reservoir (Warwick Reservoir), replacing Council’s existing small balance tank near Leslie Dam.
    Will the pipeline be above ground?

    While the pipeline route and design are still being confirmed, most of the pipeline will be underground. Once the design and route alignment are finalised, we will share the details with the community.

    Will the pipeline impact water security?

    Seqwater will facilitate an agreed operations strategy for the Toowoomba to Warwick Pipeline in consultation with the Toowoomba and Southern Downs regional councils and the Department of Regional Development, Manufacturing and Water.

    Wivenhoe Dam provides more than 286,000 megalitres to customers in Brisbane and South East Queensland each year. This includes 10,000 megalitres that can be taken by Toowoomba Regional Council when its local supplies run low.

    A volume of up to 2,665 megalitres per annum required by the Southern Downs during drought is less than one percent of the water available from Wivenhoe Dam.

    It does not impact the amount of water that Toowoomba is allowed to take from the dam. Toowoomba Regional Council residents will not have their water security affected by the separate supply to the Southern Downs Regional Council, if it’s required during prolonged drought.

    What community consultation will be undertaken as part of the project?

    The Department of Regional Development, Manufacturing and Water undertook consultation in 2022.

    Seqwater will speak to affected property owners as details of the route are finalised. Seqwater will advise the community of the pipeline route once confirmed and is committed to working with the community as the project progresses.

    What measures will be taken to protect the local environment during construction?

    As part of the planning and delivery for this project, Seqwater has undertaken extensive ecological and other environmental investigations. Both desktop and field surveys were used in the investigations, to identify and ground-truth protected plants, important habitats for plants and animals, waterway environments at pipeline crossing points, and significant and locally important street trees.

    We recognise that projects can have an impact on the environment and we are committed to ensuring we minimise our impact and demonstrate environmental responsibility by meeting any legislative and regulatory requirements.

    The project has used publicly available information and field survey to identify environmentally sensitive areas along the pipeline route, and these have been thoroughly investigated. This has helped to inform locations to avoid for the pipeline route, where possible, as well as inform any mitigations needed to be in place during construction. Investigations will continue as the pipeline route is adjusted.

    What plans are in place to protect cultural heritage?

    Seqwater is engaging with the relevant Aboriginal Parties to ensure that cultural heritage is managed appropriately. The project is being designed to avoid heritage impacts, wherever possible.

    I have a local business, how will it be considered for opportunities?

    Local businesses who wish to be considered for the construction activity should register via the local suppliers and contractors register link here.
